How to use the GPA Calculator
- For each course, enter the credits (credit hours) and pick the letter grade. The course name is optional.
- Use + Add course for more rows and ✕ to remove one. Your semester GPA updates as you go.
- Tick Count A+ as 4.3 only if your school awards extra points for an A+.
- To include earlier terms, enter your previous cumulative GPA and the credits it covers to see your new cumulative GPA.
Features
- Credit-weighted semester GPA on the standard 4.0 scale
- Plus and minus grades with their point values shown
- Optional cumulative GPA from previous GPA and credits
- Add or remove as many courses as you need
- Optional 4.3 value for A+
- Remembers your courses in this browser for next time
How GPA is calculated
Your grade point average weights each grade by the number of credits the course carries, so a four-credit lab course counts more than a one-credit seminar.
- Convert each letter grade to grade points using the scale below.
- Multiply the grade points by the course's credits to get its quality points.
- Add up all quality points and divide by the total credits.
GPA = Σ(grade points × credits) ÷ Σ credits
Worked example
| Course | Credits | Grade | Points | Quality points |
|---|---|---|---|---|
| Biology | 4 | B+ | 3.3 | 13.2 |
| Calculus | 3 | A | 4.0 | 12.0 |
| History | 3 | C | 2.0 | 6.0 |
| Total | 10 | 31.2 |
Semester GPA = 31.2 ÷ 10 = 3.12.
The 4.0 grade scale
| Grade | Points | Common percentage range |
|---|---|---|
| A+ / A | 4.0 (A+ is 4.3 at some schools) | 93–100 |
| A− | 3.7 | 90–92 |
| B+ / B / B− | 3.3 / 3.0 / 2.7 | 87–89 / 83–86 / 80–82 |
| C+ / C / C− | 2.3 / 2.0 / 1.7 | 77–79 / 73–76 / 70–72 |
| D+ / D / D− | 1.3 / 1.0 / 0.7 | 67–69 / 63–66 / 60–62 |
| F | 0.0 | Below 60 |
The point values are used by most US colleges, while percentage cut-offs vary from school to school and even between instructors. Pass/fail, audited and withdrawn courses usually carry no grade points and are left out of GPA, so do not add them here.
Cumulative GPA
To combine this term with earlier ones, you need your previous cumulative GPA and the credits it covers, both shown on your transcript. The calculator turns the old GPA back into quality points and adds the new ones:
Cumulative GPA = (previous GPA × previous credits + this term's quality points) ÷ (previous credits + this term's credits)
Example: a 3.50 GPA over 30 credits plus the 3.12 term above gives (105 + 31.2) ÷ 40 = 3.41. The more credits you already have, the less a single term moves the total, which is why raising a GPA gets harder in later years.
Weighted vs unweighted GPA
This calculator gives an unweighted GPA, where an A is worth 4.0 in every class. Many high schools also report a weighted GPA that adds a bonus, often 0.5 or 1.0 point, for honors, AP or IB courses, so it can go above 4.0. Because the bonus differs between schools, colleges often recalculate applicants' GPAs in their own way.
Tips
- Check how your school rounds. Some cut off after two decimals (3.419 becomes 3.41) instead of rounding.
- Retaken courses are often replaced rather than averaged; follow your registrar's policy.
- Planning ahead? The Final Grade Calculator shows what you need on an exam, and the CGPA to Percentage converter handles 10-point scales.
Frequently asked questions
How do I calculate my GPA?
Multiply each course’s grade points by its credits, add the results, and divide by your total credits. The calculator does this automatically as you choose grades.
How do I calculate cumulative GPA?
Multiply your previous GPA by the credits it covers, add this term’s quality points, and divide by all credits combined. Enter your previous GPA and credits in the optional section to get it instantly.
Do courses with more credits affect GPA more?
Yes. GPA is weighted by credits, so an A in a 4-credit course raises your GPA more than an A in a 1-credit course.
Are pass/fail courses included in GPA?
Usually not. Pass/fail, audit and withdrawn courses typically earn credits without grade points, so leave them out of the calculator.
Is an A+ worth 4.0 or 4.3?
It depends on the school. Most cap grades at 4.0, but some award 4.3 for an A+. Tick the checkbox if your school uses 4.3.
